AIR-EAGLE® XLT PLUS
900 MHz RF Signal Strength Tester
MODEL 461-0000
DESCRIPTION
The AIR-EAGLE XLT PLUS SIGNAL STRENGTH TESTER is a portable
battery powered unit that allows you to test the strength and reliability
of your Air-Eagle XLT PLUS 900MHz system. An LCD display provides
a bar graph to give a display of relative signal strength and a display of
total signal count, missed signals, and missed signal time.
Using the UP/DOWN and SET buttons will allow navigation of the LCD
menu. Pressing SET when START is highlighted will start the signal
counting process. When the first signal is received the TOTAL count
will start to increment. It will continue to increment at a steady rate that
matches the transmitter transmission time. If a signal is missed, the
MISS counter will increment, and the TIME counter will increment if the
maximum missed signal time has been exceeded. This will always
display the longest time that signals were missed. Press SET when
STOP is highlighted to stop the signal count and freeze the values.
INSTALLATION
1. Install the 2 AA Lithium batteries that were provided.
2. Attach supplied antenna or coax from external high gain antenna to
connector on right side of unit.
3. Turn on the power switch below the batteries. Turn the power off
when not being used to conserve battery life.

INTERPRETING DISPLAY RESULTS
The bar graph on the display shows the relative signal strength being
received. All the way full is maximum and all the way clear means no
signal is being received. The signal strength can vary greatly due to
environmental factors or interference from other RF signals.
A strong level on the meter that frequently drops out and comes back
could be an indication of strong nearby interference. Try moving to a new
frequency and see if the dropouts still occur. With spread spectrum radios
such as these, moving from frequency 1 to 2 doesn’t move it very far in
the band. It mostly just changes the hopping pattern in the same area.
Setting the frequency from 1 to 7 or 8 will move the hopping pattern up
further in the band and can help avoid local interference.
If you’re at a pretty close range to the transmitter yet have a low signal
strength this could be an indication of something blocking the line-of-sight
of the antennas or something such as a faulty antenna cable, broken
antenna or a weak transmitter module. Situations like getting water in the
antenna connector could cause this also.
Low signal where the bar disappears frequently is a sign of being on the
fringe of the reception area. Either get closer or try to get the antennas
higher up. Antennas close to the ground lose a lot of signal to the ground.
Use the running TOTAL/MISS counter to determine the frequency of
missed packets or length of drop out time. Most BWI Eagle receivers have
a relay safety delay timer of 5 seconds. This means that if the signal
holding the relay on disappears for 5 seconds then the relay will turn off.
While running the signal counter you should want your total missed signal
time to be below this, otherwise you’ll get relay chatter when the relay
drops then comes back on when it gets a signal again.
The reasoning for the safety delay timer is so that if an OFF command is
transmitted and missed then the relay will shut off in due time. The off
command is only sent for a short period so if interference blocks the signal
it won’t turn off the relay.
In applications where this timing is not critical such as well pump systems,
we can extend the safety delay timer to a much longer period. The ‘TIME’
reading on the display can give you a good idea of how long this time
needs to be. At the worst case if the transmitter sends a signal to turn the
pump off and it’s missed, the pump will stay on for the safety delay period
then turn off.
In situations where relays need to respond immediately, the transmitter
and receiver will need to be placed so that the missed packets are at a
minimum.
